On July 27, in the production workshop of Shandong Huake Semiconductor Research Institute Co., Ltd. (hereinafter referred to as "Shandong Huake") located in Jinan High-tech Zone, the temperature sensor chip HK1020, which was independently designed and developed by Shandong Huake and can completely replace the imported temperature sensor chip, was officially put into mass production after grinding, crystal fixing, wire bonding, packaging, testing and calibration. HK1020 chip, actually only millet grain size this hk1020 chip only millet grain big. "Don't underestimate this'little rice grin'. It contains dozens of layers of circuit boards and requires dozens of photolithography. It has high temperature measurement accuracy and sensitive response." Shandong Huako production and technical personnel Jin Hangfei said. The HK1020 temperature sensor chip can provide a measurement resolution of 9~12 bits, its temperature measurement range is -55 ℃ ~ +125 ℃, and its temperature measurement accuracy is ± 0.5 ℃ in the range of -10 ℃ ~ +85 ℃, which is suitable for various temperature control systems. "Compared with the similar product 18B20, which had a monopoly position in the world before, our product has better temperature measurement accuracy and 20% lower price. It is fully capable of replacing similar foreign products." Shandong Huako marketing department head said. Shandong Huako HK1020 temperature sensor chip has just been mass produced. 35 customers in Shandong and 27 customers in Shenzhen have come to order. Shandong Huaco has another 2 new temperature sensors to be launched soon. The first temperature and humidity sensor chip has also been designed and will be mass produced by the end of the year. Application of sensors in mobile phones and bracelets Sensor chips are closely related to people's lives. Air conditioning automatically adjusts temperature and humidity, reversing radar perceives things, mobile phone face recognition, unmanned driving, etc., are all inseparable from sensors. "Sensors are like human eyes, nose, ears, and skin. Its sensitivity determines the sensitivity of smart terminals." Ge Jiannan, general manager of Shandong Huaco, revealed that at present, the scale of China's sensor chip market exceeds 200 billion yuan and continues to grow at a high speed. Due to the late start of technology, it has been monopolized by foreign enterprises. Shandong Huako Production Workshop In May 2018, with the help of the technical cooperation advantages of the Semiconductor Research Institute of the Chinese Academy of Sciences, Shandong Huaco was registered and established in Jinan High-tech Zone. The company's research and development team to accelerate the transformation of technological achievements, currently has detection, small signal amplification, analog-to-digital conversion, calibration algorithms and other invention patents, integrated circuit layout protection and software copyright. Shandong Huako has completely independent intellectual property rights to the first temperature sensor HK1020. Shandong Huako High Precision Digital Smart Sensor Project is listed as a major project in Shandong Province in 2020. They are committed to building China (Jinan) Smart Sensor Valley and promoting the development of sensor chip industry chain clusters. "We strive to 3-5 years to the Chinese 'core' brand to the world." Ge Jiannan introduced.
